To all whom ent may concern:

153e itlnown that I, .lo-HN 1?.'S'Mi'in, e

Jereey City, int/lie county ofH'dsonand State of Newv Jersey` have invented a nevr and useful` `Improvement in Resilient Ambulance Cote and Streteliers, of which theV following is a specification. i

VIn the nceompanylng drawings.. .which .wei-ve. to illustrate my invention, Figure 1.

is a side elevation ofmy improved ambillance Vcot yand stretcher", showing by the dotted, lines. the means by which Said cot muy be thrown into anv inclined position. .Fig B'is a detailed section of the releasing end of cot showin spring pin holding stretcher in a locke" poeition. Fi 44 liS n detailed section ofV the counter alanced brace, Fig.` 2 is a front vertical sectional View through 2&2 of Fig. 1.

This invention relates to certain .improve-k ments in cots'ond 'stretchers, sueli .as -ar'e expie'sely deerigned for ombulancefincl hoeL pitnlsei'vice, .and the object-of the invention is to provide ,a cot with ay stretcher in coin-` 4bination simple, strong and iiiexpensiv'e,nnd

atth'e same time giving ease and 'comfort tothe patient! v v Iii the ambulances of toyday, the arrange, ment en iployed to receii'e the patient. within' 4the ambulance, also for removing thefpatient therefrom, n;-i eoniplicnted and requires the s( vices-tof o Person inside thoainbnlai'l'oe to iid] iSflhf! teo o1-Stretcher, While" the,4 present. invention such i not the ease, the ari'nngenigenthof the deiice being ofsuch ai peculiar construction that, the bed i jorti'oln of the same iiponwliieh the 'patientl les can be thrown rearward to rest in: an inclined position whereby the bed which Vcouetitutes the etre'teheit will project from the ieai'4 of the Wagon 'to suoli an extent that the Stretcher bea ring the patient can be removed from the body ofthe eotue'asily; aise on .ac 'count of the stretcher being inovabljr con.- ne'etedhtli 'exime can be drawnv ou't still far.- ther until theeooond ierson enabled to take tbe necessary hold "at front handles to eher entirely 'from the body. lThe dottc'ejd4 linesV shown in Figi '1 `of the drawinge represent the upper pontion ofthe 'not thrown backward to assume an inclined posit-ion as aforesaid. Also the supports yof tflle cot being eonatiucted of spi-ings incased in n shell or tube answer a two-fold purpose laid to engage the rfaiclrolleis in' that they serve not las;liege to the .device but also aord resiliency-to the bed'. 4citiyen of the UnitedSLa'teSM, Iresiding Vat4 shown' in Fig. 1` thel device' tali-ee' the ably attached thereto, arranged tn be'lifteil v therefrom to assunte the .form ofi. stretehol.'
